SPECIFICATION forming part of Letters Patent No. 614,100, dated November1 5, 1898.

Application filed February 4 1898. Serial No. 669,133. (No model.) I

To all whom it may concern:

Be it known that we, ALFRED HENRY GRIF- FITHS, residing at Surrey Works,Smethwick, and EDWARD THOMAS READ, residing at 75 Thornhill road,Handsworth, in the county of Stafford, England, subjects of the Queen ofGreat Britain, have invented new and useful Improvements inLamp-Fittings, (for which application for patent has been made in GreatBritain, No. 16,688, bearing date July 14, 1897, also application forpatent in Germany, No. 19,943, hearing date September 25, 1897, and alsoapplication for patent in France under No. 262,134, dated January 25,1898,) of which the following is a specification.

Our invention relates to improvements in lamp, chandelier, and the likefittings, and is chiefly intended to accommodate incandescent-lightfittings; and its primary object is to provide improved means wherebythe screens or eye-shades for such lights may be more convenientlycarried than hitherto or removed at will, also improved facilities forcarrying ornamental scrolls or the like from such fittings and theirburners, both of which purposes are effected without fixed attachmentsor other interference with the down-rods or stretchers or other similarrods used in their construction. We attain these objects by the meansillustrated upon the accompanying drawings, upon which-"- Figure 1 givesa general View of our in- Vention adapted to a fitting having anincandescent gas-burner. Fig. 2 is a plan View, and Fig. 3 a sectionalview on line A B of Fig. 2, of the supporting-ring hereinafterdescribed. Fig. 4 is a semi-view in elevation, and Fig. 5 a plan View,of the principal part of the burner. Figs. 6 and 7 each show a modifiedviewof yielding means of supporting the ring upon the flange of theburner. Fig. 8 shows how the ring may be carried from the lower part ofthe burner.

Similar numbers refer to similar parts throughout the several views.

Hitherto much inconvenience has been experienced in carrying the screensof these lamps having downhanging stretchers or rods by reason of theirbeing carried or supported from the rods themselves, for which purposevarious forms of attachments have been fixed upon the said rods in orderto carry such screens. As will be readily seen, these contrivances arequite unsuitable for screens which may be outside the rods and in anycase where the support has been secured to the rods. Also attempts havebeen made to ornament such rods by means of scrolls carried upon them.It is therefore found desirable that the screening, either within orwithout the rods,.should be done Without interference with the rods, sothat they may be placed in position or removed from position withoutinterference with the burner; also, that a more general means ofornamentation be effected both above and upon and below the burnerwithout interference with the rods.

We effect these improvements by our invention as follows:

Referring, for instance, to what are known as downhanging lamps, asshown in Fig. 1, as is well known the burner 10 is carried at the lowerend of and between two rods 11. Such burners are made with threeoutstand i-ng spurs or projections 12 (see Figs. 1, 4, and 5) and alsowith a horizontal flange 13. We

provide the removable ring 14, (see Figs. 1, 2,,

and 3,) upon which is carried the screen 15. This ring is shown toencircle the rods 11; but it will be readily seen that if the rods aremade wider apart for any reason then the ring may be within them.Generally when it is so made to lie within. the said rods it is onlyused for carrying the ornamental scrolls.

Upon the under side of this ring 14 (see Figs.

2 and 3) are three grooved projections 16, which correspond to and restupon the three spurs 12, so that the ring is carried thereon, as seen inFig. 1. In orderto preserveafixed relative position of the ring with therods 11, the. guides .17 are used to embrace them, so that having passedthe ring upward from below the fitting the burner is turned around untilits spurs are directly beneath the grooved projections 16, when the ringmay be lowered thereon. In some cases we may carry the said ring fromthe flange 13 or other similar part, which may be done by making theprojections 16 or similar projections sufficiently long to reach andrest uponvthe said flange. In such cases,where it is required that thering shall be passed upward from below the burner, one at least of suchprojections must be made to move out of the way of the flange in orderto pass over it. This may be done, as seen in Fig. 6, by means of thespring-back bolt 18, which takes the place of one or more of theprojections 16,01 one or more of the projections may be substituted bythe lever device shown in Fig. 7, which maybe similarly moved out of theway to pass the flange 13 and then brought back into its proper positionto rest upon the flange. Screw -pins maybe used, if desired. \Ve mayalso carry the ring 14 by means of a lower collar 19, (see Fig. 8,) theornamental scrolls 2O serving to connect it with the ring 14:, inaddition to their ornamental service. The collar 19 may be made to restupon the shoulder 21 of the burner, or it may be-screwed between theburner and'the frame at 22.

It will now be readily seen that upon the ring 1 1 we may mostconveniently carry ornamental parts or scrolls, such as 20, andparticularly does this enable us to ornament those parts which havehitherto received little or no ornamentation, such as immediately aboutor below the burner, and such ornaments are thus carried withoutanydifiiculty of fixing or interference with the necessary attention tothe lightsuch as cleaning, lighting, &c.-and at the same time leavingthe rods 11 quite free.

\Nhat we claim, and desire to secure by Letters Patent, is-

1. The combination with the burner 10, having spurs 12, of thesupporting-ring14,whose uppersurface is adapted to receive the screen15, such ring having the projecting carriers 16, and ornamental scrolls20, substantially as set forth and shown, and for the purposesspecified.

2. The combination with the ring 14, removably carried upon the spurs12, of the burner 10, and having the ornaments 20, with the rods 11, andguides 17, as set forth and shown, and for the purposes specified.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
